Take the purple line off at the secondary filter, crank it over with the starter and see if the pump is at least pumping fuel on its own.... those old Detroit's had a restrictor valve where the fuel line comes back out of the head on the return to the tank... if that valve is plugged with crap, it won't run either.
I did have the (GREEN) line loose at one point and cranked the engine and did get some fuel to come out but not as much pressure as I expected. ??
So, the pump is at least working some...
It sounds like I do need to take the return hose loose. I never thought about there being a return.
That would pretty much make pressurizing the tank not really do anything. Need to find and check for a restrictor valve.
The cylinder head holds enough fuel to run about a minute or two.Sounds like the gear type charge pump at the end of the engine did not prime.You may want to start by putting a small fuel supply above the charge pump,get a syphon going then plug into the charge pump and crank.The cylinder head acts as a fuel tank of sorts,as long as it's full it feeds the injectors.When it's full it returns to the tank.
So the fuel isn't under pressure? You almost make it sound like it is just a tank up there or something. ??
ddiiggy, sorry to have hi-jacked this thread! Have you had time to check that emergency shut down? That's just a large flapper plate blocks off the air to the engine when the release is operated. I would also suggest removing the valve cover and check to see if the linkage that operated the fuel injectors is working free. One thing to look for is if there is any clearance between the injector rocker arm and the top of the injector plunger if there is then the injector is stuck and I would not try starting till I had replaced them. One stuck injector can hold all the others in full fuel position and cause the engine to runaway and you will only have a few seconds to kill the engine with the emergency shut down. That is one reason why you should make 100% sure that works first of all.
hi-jack away. I'm sort of waiting on some warmer weather to really get back into this. It's not like it is a big hurry. It has been sitting for a while.
I'm not really needing to USE this thing, I just want to get it moved from where it is setting.
I did check the action of the air intake flapper. It does move. It just has a catch and then it goes the rest of the way.
I will take off the whole cover and check the flapper and watch the blower...
Time to figure out how rusted in the bolts are that hold the lid on so I can see inside the valve cover.
